Soil structure is the spatial arrangement of solids and pores at scales smaller than the soil horizon, and consists of clusters of solids and pores called aggregates, that have hierarchical, emergent properties, and memory that define their functions. From: Geoderma, 2023

Burland (1990) proposed an intrinsic compression line (ICL) in the \({I}_{\text{v}}\)-log \({p}_{\text{c}}\) space, which was obtained from compression data, the void index (\({I}_{\text{v}}\) (Low et al. 2008), of various reconstituted clay samples. The definition of void index is shown in Eq. (1): where \(e\) is the void ratio under consolidation...
The structure yield is an important characteristic of structured soil through the one-dimensional compression test. Considering this deformation characteristic, Cotecchia and Chandler (2000) and Chandler (2000) established a sensitivity evaluation system in 2000, which used a structured index, viz. stress sensitivity, to quantitatively describe the...
The shear strength characteristics of soil reflect the influence of the structure of natural sedimentary soil on the structure strength. Accordingly, based on the results of unconfined compressive strength test, the sensitivity is used to evaluate the structure characteristics of soil by many researchers (Lu 2002; Yin 2007). The sensitivity of soil...
Based on the thinking of CSP, various structural parameters of soil were proposed (Xie and Qi 1999; Chen et al. 2006; Shao et al. 2004, 2006 and 2010; Shao and Deng 2008; Luo et al. 2004; Deng 2009), as listed in Table 6. Compared with the stress sensitivity and sensitivity, these structural parameters are obtained through many tests under complex ...
Abstract. Soil structure and soil organic matter (SOM) have an interactive relationship and mediate all soil processes at all spatial and temporal scales. Soil structure and SOM can be degraded through land use, tillage, compaction, and climate change mechanisms.
Jan 1, 2005 · Soil structure influences soil water movement and retention, erosion, crusting, nutrient recycling, root penetration and crop yield. Externalities such as runoff, surface- and ground-water pollution and CO 2 emissions are influenced by soil structure.

Jul 29, 2015 · Soil Structure. Soil structure is the description of how individual soil particles (sand, silt, and clay) are arranged into soil aggregates (also called peds) and reflects both physical and chemical weathering. Several factors influence soil structure, including soil texture, soil moisture, organic matter content, compaction, the activity of ...
